cephadm: Make vagrant usage more comfortable
Currently you can only use a big scale factor using the vagrant setup. You can have x * (mgr, mon, osd with 2 disks). It would be nicer to use the same constants as vstart is using to select how many mgr, mons and osds one likes to have. I would go further and add a disks constant two.
This would make the creation a lot more flexible. Another thing that is missing is an script to easily snapshot the created vm's and recreate them
